Sandisk Surges Ahead as Seagate Struggles in AI Storage Race
Sandisk’s rapid revenue growth signals the shift to NAND flash memory in AI data centers, leaving Seagate behind.
AI data centers demand speed and efficiency, and Sandisk is delivering that with its NAND flash memory. Their revenue doubling in a single quarter highlights how quickly the market is moving away from traditional hard drives, where Seagate still competes. For South African investors, this matters because tech companies like Naspers and Prosus have stakes in global AI infrastructure and cloud services that depend on fast storage solutions. The USD/ZAR rate can influence the cost of importing such tech, so a weaker rand would make Sandisk’s products pricier locally. Seagate’s steady growth shows it’s not dead, but it’s clear the hard drive era is fading under the AI spotlight. If NAND flash continues to dominate, consumer tech and data-heavy sectors here could feel the impact — positively for firms tied to newer tech, negatively for those lagging. That said, if a breakthrough revives hard disk tech or AI adoption slows, this narrative could change. this is just my opinion and not financial advice
I would watch Prosus and Naspers for exposure to AI-driven tech shifts but remain cautious on any hardware suppliers dependent on legacy storage tech. Keep an eye on USD/ZAR moves that affect import costs.

6/10
Sandisk has dramatically overtaken Seagate Technology in quarterly revenue, driven by surging demand for NAND flash memory in AI data centers. While Sandisk's Q2 2026 revenue reached $6.0 billion with forecasts of $7.8-8.3 billion next quarter, Seagate's steady growth to $3.1 billion reflects slower adoption of its traditional hard disk drives in the AI ecosystem.
